IMPROVEMENT IN BOLT-HOLDERS.

The Schedule referred in in these Letters Patent :ind making part i thesame.

l, SPICER R. BUTTERFIELD, of Rome, in the county of Oneida and State ofN ew York', have invented an improved Bolt-Holder, kof which thefollowing is a specification.

Nat-ure and Objects 0f the I nvention.l

My invention consists of a tool to hold the head of a bolt firmly jammedagainst the object, so that it may not be turned by the applicationofthe wrench to the nut.

Description of the Accompanying Drawing. The device is' exhibited by aperspective view.

General Description..

A is a two-pronged claw, designed to catch over an object through .whichthe boltris passed, and leave an opening between the prongs, which maybeoccnpied by the nut, and gives facility for the movement of the jawsof the wrench.

At the heel of the claw A a nut, B, is swiveled, having bearings in thecheeks, l) l), of the claw.

Through this swivelefl nut passes the screw C, which has a point, c, anda handle, D. l

Operation. The claw A bein" hooked over an obeot and the bolt Idriventhrough the saine, the screw C is retractedl or advanced to such anextent as to allow the point c to be forcibly driven against the head ofthe bolt, to press it rinly againt the object through which it has beenpassed.

The nut, being placed on the threaded portion of the bolt whichprotrudcs through the object, is then screwed home to its seat againstthe side of the object opposite to that against which the head ot' thebolt is pressed.

'lhe distance between the prongs allows the nut to be applied, and alsogives room for the jaws of the wrench to revolve with the nut withoutinterference by the claw.

Claim.

What I claim as new is- The tw0-pronged claw A, furnished with aswxveled nut, B, and a pointed screw-shaft, C, substantially asdescribed and represented.
